@daviwil And in the end for example I have the choice between learning Common Lisp and where the quirks lie, or the absolutely brilliant but separate languages/ways of doing stuff in Guile, Racket, Chez, ...
That's my feeling and I am ofc using Guile right now for many of my things, it was a strange choice to make in the beginning and hadn't it been for Guix I wouldn't have been able to make it I think.
@michal_atlas @daviwil you can use r7rs by starting guile with --r7rs, or in the repl with
> ,use (scheme)
> (install-r7rs!)
Guile's r7rs and r6rs support is pretty good, but not complete, and there are some tiny divergences you have to figure out. But its good enough to build akku.
